A Novel Control Strategy for Power Sharing Enhancement of an Inverter-Based Microgrid

Overview

An innovative power sharing strategy is put forward for active power-frequency management of a couple of inverter interfaced distributed generators encompassed in a microgrid. The presented strategy employs two cutting- edge droop based methods called unit power control (UPC) and feeder flow control (FFC). FFC outperforms UPC in terms of both grid-connected and islanded operation of microgrid. These methods are modified to enrich the transient response of distributed generators concurrent with the steady state behavior. A combination of these methods is applied to control generators of a microgrid where results of numerical time domain simulations substantiate the superiority of the enhanced edition control strategy.
